Learn homeopathic repertorization

Repertorization is two skills: translating a patient's symptoms into the standardized rubric language of the repertory, and reading the resulting remedy chart without being fooled by it. Software, grading schemes and elimination tricks decorate those two skills. Learn the method in six steps, on paper first.

A repertory is an index of symptoms with the remedies recorded under each. A rubric is one indexed entry. Repertorization is the procedure that follows.

Step 1 — Take the case before touching the book

Repertorization operates on a finished case record, not on a live conversation. The case-taking standard is Hahnemann's: record the patient's account in their own words, complete each symptom with its location, sensation, modalities and concomitants, and interfere as little as possible (Organon §83–§104). A symptom without modalities — what makes it better or worse — is usually too vague to translate into a rubric at all.

Step 2 — Select the characteristic symptoms

This step decides the quality of everything downstream, and its criterion is §153: the striking, exceptional, unusual and peculiar signs carry the selection, not the symptoms common to the diagnosis. A practical selection pass over a written case:

1. Strike out symptoms every patient with this complaint would have — they individualize nothing.
2. Flag strange, rare and peculiar symptoms — the §153 material.
3. Flag strong mental and emotional generals, and physical generals (reactions of the whole person: temperature, thirst, sleep, time aggravations).
4. Keep well-modalized particulars — local symptoms with clear conditions attached.

Kent's hierarchy holds throughout: generals outrank particulars, and the peculiar outranks the common at every level.

Step 3 — Translate symptoms into rubrics

Now the repertory opens. For each selected symptom, find the rubric whose wording matches at the right level of generality. Two disciplines keep the translation honest. First, prefer the rubric that says what the patient said, not the one that says more: a patient wakeful from thoughts is Sleeplessness from thoughts, not a broader anxiety rubric. Second, check the rubric's size — very large rubrics (hundreds of remedies) discriminate weakly; very small ones gamble the analysis on the record's completeness. In Kent's Repertory the head-to-foot chapter architecture is itself the classification scheme, and learning that structure before searching it pays back every hour spent on it.

Step 4 — Grade the rubrics

Classical method weights each rubric by its importance in the case before any counting happens — typically a 0–4 scale, with mental and physical generals and §153 symptoms at the top, well-modalized particulars in the middle, and merely-present symptoms at the bottom. Grading is clinical judgement entering the arithmetic. Two students grading the same case differently will get different charts, and that difference is where the case actually lives.

Step 5 — Read the chart, do not obey it

The analysis produces a table: remedies in columns, rubrics in rows, a coverage score per remedy. The score is a sorting device, not a verdict. Read the chart for which remedies cover the §153 symptoms and the strong generals — a remedy that misses the case's one truly peculiar symptom rarely deserves the prescription however well it covers the common rubrics. Elimination technique — confining the analysis to remedies present in one mandatory rubric — sharpens charts and carries a known risk: one misjudged rubric excludes the correct remedy from consideration entirely.

Step 6 — Confirm in the materia medica

The repertory indexes the literature; it does not replace it. The final step is always reading the top candidates in a materia medica — Boericke for speed, Hering or Allen for depth — and asking whether the remedy's portrait matches the living case in front of you. Kent's order of operations is explicit: repertorize to shortlist, read to decide.

Practicing the loop, and where software enters

The training regimen is the weekly paper case: published case in, written remedy commitment out, scored against the recorded prescription. Once the paper method is stable, software removes the clerical friction without changing the six steps — rubric grading from 0 to 4 and an automatically saved analysis chart inside each case accelerate steps 3 to 5. A genuinely instructive exercise: repertorize the same case on paper and in a tool, then explain every difference between the two charts. Working students can run that exercise inside the free repertory and case analysis at Similia.

The common errors, named

• Repertorizing common diagnostic symptoms — the chart then ranks remedies for the disease, not the patient.
• Over-large rubric choices that flatten every remedy to the same score.
• Treating the numeric ranking as the prescription.
• Skipping materia medica confirmation.
• Letting search suggestions substitute for symptom classification.
